| 摘 要： | 在温和条件下，以３－氨丙基三乙氧基硅烷为偶联剂，修饰介孔分子筛 ＭＣＭ－４１（Ｓｉ／Ａｌ＝３５），成功地将有机官能团引入到介孔分子筛孔道中，制备了一种无机一有机复合材料ＭＣＭ－（ＣＨ２）３ＮＨ２，以 ＸＲＤ、ＦＴＩＲ、ＤＴＡ－ＴＧＡ、 Ｎ２吸附－脱附和 ＨＲＥＭ表征了复合材料；结果表明：有机基团－（ＣＨ２）３ＮＨ２不仅进人孔道、修饰了ＭＣＭ－４１的孔壁，而且使介孔分子筛ＭＣＭ－４１保持了有序的孔道结构．

| Abstract: | Under mild experiomental conditions, with 3-aminopropropyltriethoxysilane as the cou- pling agent, mesoporous molacular sieve MCM-41(Si/Al=35) was modified, and -(CH2)3NH2 or- ganic functional group was successfully introduced into the pore of the mesoporous sieve,the or- ganic/inorganic complex material MCM-(CH2)3NH2 was synthesized, and characterized by XRD, FTIR, DTA-TG, nitrogen adsorption-desorption at 77K and HREM. The results of the character- ization show that -(CH2)3NH2 not only gets into the modified inner wall of mesoporous MCM-41, but also makes MCM-41 remain its ordered pore structure. |
